And, because the 9mm Luger delivers less recoil, you can put more shots on target faster. In similar-sized handguns, it can also hold more ammunition. 45 ACP: Making the Right Choiceįinally, the 9mm can be housed in smaller and lighter handguns. Since both end up at about the same diameter, and both penetrate about the same distance, what else really matters? Thirdly, ammunition for both cartridges can be designed to deliver more than a foot of penetration in a human body. A bullet fired from a 9mm Luger has twice the rotational velocity of one fired from a. This, in conjunction with the faster twist rate of 9mm barrels, makes it easier to design bullets for the 9mm that will reliably expand over a broader velocity spectrum. 45 ACP - it launches its bullets much faster. Secondly, because the 9mm Luger operates at a higher pressure - 35,000 psi as opposed to 21,000 psi for the. Much like the shadows they cast, from a terminal performance standpoint, there is really not much difference in the 9mm, 40 S&W or. After the bullet deforms due to impact, the difference in diameter is really what matters, and that varies a lot. That’s just a shade larger than the thickness of a quarter. 45 ACP bullet is exactly 0.095 of an inch larger in diameter than an unfired 9mm Luger bullet. Ok, let’s consider the facts, and disregard the hype, so we can better understand this squabble.įirst of all, an unfired bullet. 45 ACP shoots a larger-diameter and heavier bullet, therefore it has to be better. Here’s the thing: There’s no definitive way to prove which cartridge is better. 45 does fire heavier bullets, a 9mm gun generally has more capacityĪre you as sick of hearing this argument as I am? This has been an ongoing debate for more than 100 years. Both cartridges can be designed to deliver more tha a foot of penetration in a human body.Unfired there's only 0.095-inch difference between.But in the end does one cartridge really outperform the other? How does the. Between these two, shot placement and bullet performance will matter more. However, it shoots it much faster, with much less recoil, and 9mm handguns have a higher capacity. Yes, the 9mm Luger shoots a smaller caliber and lighter bullet than the.
